c++ input hexadecimal without 0x

Question

I'm making a project that dumps a file by putting the offsets (hexadecimal). I must put the hexadecimal with 0x like 0xBEE4DC because the application will crash or return an error if I put a hexadecimal without 0x like BEE4DC. Is there a way to put the hexadecimal without "0x" ?

This is my code. i'm keeping this project secret so I don't show more code than this.

dump1.cpp

void LoadMetadata(char* szFile)
{
    string mystr;
    int offset2;
    int offset1;
    std::cout << "Input unknown offset #1: ";
    getline(cin, mystr);
    stringstream(mystr) >> offset1;
    std::cout << "Input unknown offset #2: ";
    getline(cin, mystr);
    stringstream(mystr) >> offset2;
    std::cout << "\n";

    ...

}

dump2.cpp

static int offset2;
static int offset1;

void LoadDumpLib(char* szFile)
{

...
    pCodeRegistration = (DumpCodeRegistration*)MapVATR(offset2, pLibIl2Cpp);
    pMetadataRegistration = (DumpMetadataRegistration*)MapVATR(offset1, pLibIl2Cpp);

...
}

This code should work

std::cout << "Input unknown offset #1: ";
getline(cin, mystr);
stringstream(mystr) >> hex >> offset1;
std::cout << "Input unknown offset #2: ";
getline(cin, mystr);
stringstream(mystr) >> hex >> offset2;
std::cout << "\n";
